Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709806, here are decompositions:

13 + 8709793 = 8709806
109 + 8709697 = 8709806
337 + 8709469 = 8709806
433 + 8709373 = 8709806
577 + 8709229 = 8709806
619 + 8709187 = 8709806
673 + 8709133 = 8709806
727 + 8709079 = 8709806

Showing the first eight; more decompositions exist.
